Dear Sir/Madam,

Because of the recent recurring issues we had affecting one of our routers(next hop-74 / 174) in the Wuppertal DC, we will proceed to redesign that section of the network and change default routing policies. The changes will be done in the course of this/next week between 05:00 – 14:30 GMT.
Traffic impacting changes will be done between 05:00-07:00 GMT.
We will do our utmost to not affect any traffic after 7:00 AM but servers with very low traffic/ip's not in use might experience reachability issues. Should you experience any problems with your ip's, please contact us asap.
